Hi all !
I have rerun the all process for creating a microblaze platform on the ML402 board with fs-boot and the same parameters than my successfull build
except the microblaze core frequency that I set at 400MHz.
I successfully generate the bitstream using Xplorer Scripts, unfortunately, fs-boot doesn't start.
You didn't get any warning/errors about missed constraints ?
Check again
No I don't with the Xplorer Scripts option (you can test it as well ;)
and well, as Bruce said and as I understand now, what I had setted is just the input clock ...
I presume that the "Reference Clock Frequency" is then used to synchronize with other logic on the FPGA at that frequency, and for a XPS only board project there is no reason to use something else than the default value.
Am I right ?
I though that they where a freq for the CPU core and a freq for the peripherals on the bus.
